IMPROVEMENT IN SPINNING-MULES.

Specification forming part of Letters Patent No. 56,133, dated July 3,1866.

To all 'whom it may concern:

Be it known that I, ROBERT WILBE, of the city of Philadelphia, in theState of Pennsylvania, have invented a new and useful Improvement inSpinning-Mules; and I do hereby 'declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the accompanying drawings, making a part ofthis specification, in which- Figure lis a side elevation, and Fig. 2 anend elevation, of a spinning-mule head, showing I my said improvementapplied thereto, Fig. 3

being a plan View of the detached sliding rod or bar, in connection withthe weight, pulley, and the levers which immediately operate to connectand disconnect the gear-wheels of the mule-head, like letters ofreference indicating the same parts when in the different figures.

The object of my improvement is to produce and apply an apparatus whichwill be more efticient, as well as more simple and less costly inconstruction, and also more durable in use, for putting the roll andscroll wheels of a spinning-mule in and out of gear during the movementsof the carriage; and the nature of my said invention consists in theemployment of a weight, or its equivalent, in connection with a slidingrod and levers on the mule-head and operating studs or projections onthe carriage, constructed and operating substantially as hereinafterdescribed. v

In the drawings, A B is the frame of th mule-head; C, a representationof one of the positions of the carriage; D, the weight; E, the slidingrod; F, its operating-lever; Gr, its sustaining-lever; H, thegear-detaching lever, and I and J the two operating-studs'on the end ofthe usual carriage. y

The sliding rod E is attached to the side of the mule-head frameAB, andhas two mortises or slots, e' e', in which its sustaining-lever G andits operating-lever F, respectively, work, the notched end g of theformer sustaining or holdin g the sliding rod E, both in its advancedand retracted positionsl alternately, an d the lever F, passing throughthe slide E and extend-f ing downward, serves as a means ofadvancing thesaid slide E, and also of elevatin g the retracting-weight D. Theopposite end of the slideE passes loosely through a boss, l, on thelower end of the usual scroll-wheel lever l', and has a head, e2, on itsextreme end, whereby the said lever l is caused to lift the usualscrollwheel 2 into gear with its pinion above, when the slide E isretracted by the weight D,which is suspended by a cord over the pulleyd', as will hereinafter be described. Also, on the said slide E there isfixed a boss, e3, which has a short arm extending upward, and servin'gto catch against the horizontal arm a of the cranklever n2, whichsupports the upper end of the beveled roll-wheel o, and thus throws thelatter into gear as the said slide E-is retracted by the weight D, aswill hereinafter be explained.

The gear-detachin g lever H has one end, h',

pivoted to the frame A B, while its other end is left free to be movedup and down in a guide, h2, also attached to the frame. Fixed to andprojecting downward from the said lever H are two curved rigid arms, h3h4, of such lengths and forms that, as the end c of the carriage Cpasses, the stud J on the latter will rst strike and pass Linder the armh3, and thus elevate the lever H sufciently to release the arm a, whichis held back against the pressure'of its spring n by means of the stoph5 on the said lever H, and thus throw the roll-wheel o out o t' gear,and immediately afterward the said stud J strikes against and passesunder the arm h4, elevates the said lever H sufficiently farther todetach the scroll-wheel lever Z from its contact with a small angularstop, hf", on the said lever, which latter then rests, by the said stop,on the boss l, while at the same time the scroll-wheel Z2, which issupported by the said lever l', falls out of gear. (See the dotted linesin Figs. l and 2.)

The operation of this apparatus in throwing the roll-wheel o and thescroll-wheel L2 out of gear by the advancing or outgoing motion of thecarriage G having now been fully described, it remains to describe itsoperation in throwing the said Wheels again into gear. This is effectedby the returning oringoing motion of the same carriage, when its stud I,coming in contact with the retaining-lever G, moves the latter backwardfar enough to disengage its notch g from its slot in the slide E, andthus permits the weight D to draw back the said slide E, andconsequently, by means of its two bosses, e2 e3, to force the tworespective wheels Z2 and o into gear, as seen in the drawings.

It will be seen that this apparatus is less complicated than the oldone, that it is less liable to derangement by use, and that it is muchlighter in weight, more durable, and costs less for construction andapplication, While it is equally if not more reliable and ei'- eient forthe purpose.

I do not desire to confine myself in its construction to the use of theweight D for retract ing the slide E, and thus bringing the Wheels l2and o into gear, as it will be obvious that a strong spring will answeras an equivalentfor the same purpose,althongh I prefer the use of theWeight, as set forth; but,
